Abstract

L'invention concerne une unité filtrante à introduire de manière remplaçable dans le boîtier d'un système filtrant, qui présente les caractéristiques suivantes: (a) l'unité filtrante présente un élément support prévu pour maintenir l'unité filtrante dans le boîtier et comportant une première face et une seconde face opposée. La première face destinée au montage fait face à la chambre de gaz pur du boîtier; (b) une pluralité d'éléments filtrants individuels évidés, qui comportent chacun une surface extérieure d'afflux pour le fluide à filtrer et une zone superficielle ouverte pour évacuer le fluide filtré hors de l'intérieur de l'élément filtrant. Lesdits éléments filtrants sont combinés avec l'élément constitutif support, de manière que les éléments filtrants se trouvent sensiblement dans leur ensemble sur la seconde face de l'élément support et qu'ils exploitent bien l'espace situé sur la seconde face de l'élément support; (c) les éléments filtrants sont intrinsèquement stables et comportent des éléments filtrants composés de particules réunies par frittage de manière poreuse; (d) l'assemblage des éléments filtrants et de l'élément support s'effectue de manière commune pour les éléments filtrants par une résine de coulée qui recouvre les éléments filtrants sur la face extérieure dans chaque cas d'une couche d'au moins 1 cm de haut et resserre les zones superficielles ouvertes des éléments filtrants de manière très limitée. La résine de coulée constitue de préférence également l'élément support de l'unité filtrante.
